SPECIFICATION forming' part 0f Letters Patent No. 530,869, dated December 11, 1 894.

Application filed May 29, 18 94.

To @ZZ whom imay concern.- f

Be itknown that I, JACOB P. WEIS, a citizen of the United States, and a resident of Anderson, in the county of Madison and State of Indiana, have invented certain new and useful Improvements in Furnaces; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

Figure l of the drawings is a vertical longitudinal section through furnace. Fig. 2 is a section on line .ft-x, Fig. l.

This invention has relation to certain new and useful improvements in gas and hot air furnaces, and it consists in the novel construction and combination of parts, all as hereinafter described, and pointed out in the appended claim.

The object of the invention is to provide a furnace adapted t0 the use of natural, or other gas, combined with hot air as a fuel.

Referring to the accompanying drawings, the letter A designates the bed of the furnace upon which are erected the side and end walls B.

C is a cold air chamber, corresponding to the ash pit in ordinary furnaces. VThe roof of this chamber is formed by a horizontal wall D, usually of brick, supported upon iron grates or bars a, said wall also forming the bottom of a heating or hot air chamber, which is divided into a series of longitudinal iues E. The top wall E of this chamber and of the fiues is a sheet metal plate which also forms the bottom of a combustion chamber F. The wall D does not extend quite back to the vertical bridge wall G, but terminates sufficiently forward thereof to form a transverse opening or passage c through which the air from the chamber C rises and passes into the fines E. The space back of the cold air and the heating chamber is filled in solid, and covered with brick, which rise a little higher than the tioor E of the combustion chamber, forming a chamber G through which the salmi., 512,834. (Nomade.)

vided With any Well known or suitable device for mixing'with the gas, previous to combustion, the heated air from the flues E, thus greatly intensifying and increasing' the combustion. v

L L designate the doors to the cold air chamber, and M M the doors to the combustion chamber. These doors may be provided with any suitable form of dampers or drafts to regulate the combustion.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is f In a furnace, the combination with the bed and the vertical walls thereof, of the horizontai Wall D, forming a cold air chamber O between said wall and the bed, a series of 1ongitudinal partitions above said wall D, forming a series of iiues E, which communicate at their rear ends with said cold air chamber by a vertical. passage c between the rear end of the walt D and a bridge wall G, a wall E forming the top of said flues E, and the bottom of a combustion chamber F, a transverse gas receiving pipe in the forward portion of the chamber O, a series of burners extending from said pipe into the forward portion of f the combustion chamber, and a gas and air mixer on each of saidl burner pipes in the forward portion of each of said iiues E, and receiving the hot air therefrom, substantially as specified. v

In testimony whereof I affix my signature in presence of two witnesses. f

JACOB P. WEIS.
